ABSTRACT:
It is provided with a pair of carriage guide shafts, and the carriage guide shaft is made to be in sliding contact with a carriage, to realize such a concentric shaft configuration that a guide shaft part, which directly guides a reciprocating motion of the carriage, and rotation shaft parts, which are disposed on both ends thereof, were disposed so as to coincide therewith. In addition, by disposing parallel lifting device which utilized a cam mechanism and a lifting guide portion to side frames, the carriage guide shaft is configured so as to be able to obtain a predetermined lifting stroke which corresponds to a rotation angle. In addition, as synchronous drive transmission mechanism of the pair of carriage guide shafts, a gear wheel train was used.
